This article is about how to solve the problem that Ubuntu 16.04 can not connect to the Internet after waking up after sleep. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

The method is as follows

1. Click the terminal icon on the initiator bar on the left side of the Ubuntu desktop, or simply press the Ctrl+Alt+t key combination to start the terminal.

2. Enter the command: sudo systemctl restart NetworkManager.service, and enter.

3. The network connection icon in the upper right corner of the desktop will change to a "disconnected" state, while a bubble prompt that the network has been disconnected appears on the desktop.

4. Soon, the network icon returns to the connected state, and a bubble prompt appears on the desktop that the network is connected.

5. If you need to disconnect and start the connection later, you can use the following commands:

Sudo systemctl stop NetworkManager.service

Sudo systemctl start NetworkManager.service

6. To mention here, if it is Ubuntu 14.04, you need to use the following command:

Sudo / etc/init.d/networking stop or sudo service networking stop

The change in Ubuntu 16.04 is due to the use of systemd, while version 14.04 or older uses upstart.
